Step by step instructions, muscle activation and variants for the Elbow to Knee Sit-up.
The Elbow to Knee Sit-up is a core exercise that combines a full sit-up with a cross-body rotation, bringing the opposite elbow toward the knee at the top. It targets the abs and obliques, adding a rotational component to the traditional sit-up for greater core activation.
The Elbow to Knee Sit-up is a foundational movement that builds strength and muscle through controlled, progressive overload. Train it 1 to 2 times per week with 3 to 5 working sets per session, gradually adding weight or reps as form holds up.
